Sanitary Sewer Replacement West Pine Street Between Magnolia And Laurelton Blvd

The purpose of this project is to replace a collapsed section of sanitary sewer on West Pine Street between Laurelton and Magnolia Blvd. The collapsed section of sanitary sewer is located between the sanitary sewer manhole (MH #509) at the middle of West Pine Street and Laurelton and sanitary sewer manhole (MH #603) at the intersection of West Pine Street and Magnolia Blvd. The distance between the respective manholes is approximately Four Hundred (400) linear feet. The diameter of the existing pipe is twelve (12) inches.

The intent is to replace approximately four hundred (400) linear feet of sanitary sewer main between MH #509 and MH #603. The trench limits (width) shall be ten (1O') linear feet. The Contractor will be required to connect to the existing manholes at each respective intersection. The manholes are in fair to good condition. The contractor will be required to reconnect the existing sanitary sewer house connections to the new main. There are 16 sanitary house connections to be reconnected within the 10’ wide trench.

Refer to exhibit A for sewer replacement location and the rim and inverts of the existing sewer pipe.

Restoration shall consist of the installation of 6'' of recycled concrete aggregate and 4.5 " of asphalt (3” of base asphalt and 1.2” of top asphalt)

The selected Contractor will be required to replace an existing sanitary sewer pipe with polyvinyl chloride (PVC) sewer pipe. The existing sewer is approximately 9 feet below street elevation with the inverts of the existing pipe possibly in the groundwater. The contractor should be prepared to institute dewatering operations as needed. Due to the depth of the installation, the contractor should be equipped with the appropriate sheeting/shoring/bracing, etc. for this installation, to be used as necessary.
